Abstract

We report here the photorefractive effect in monolithic structural polyimides containing the triphenylamino-(p-nitrophenyl)-ethylene group as a nonlinear optical (NLO) chromophore and hole transfer. Three types of polyimides were synthesized to control the loading ratio of the NLO chromophore; 50, 30 and 17 mol% for polyimides 1, 2 and 3 respectively. In the two-beam coupling experiment, asymmetric energy transfer was observed in the case of polyimides 1 and 2, providing evidence for a phase shifted grating after corona-poling treatment, whereas the energy transfer of polyimide 3 was not observed. This result denotes that the NLO chromophore plays an important role in monolithic photorefractive materials, and a greater than 30 mol% concentration of NLO chromophore is required for creating sufficient space charge distribution.
